Understanding the Defect Trend Gap:

A gap between "defects opened" and "defects closed" usually indicates defects that have been resolved (fixed) but are pending formal closure, often awaiting retesting or approval.

The trend convergence suggests the defect management process is effective, but some defects are still in the verification stage.

Evaluation of Options:

Ais incorrect: The gap does not indicate projected but unfound defects.

Cis incorrect: Regression defects would cause a divergence, not convergence, in trends.

Dis incorrect: Defects introduced to production are unrelated to the convergence.

Bis correct as it aligns with the standard defect lifecycle.

References and Syllabus Alignment:

This aligns with "Defect Management" in the ISTQB syllabus, emphasizing defect lifecycle tracking (TM-2.3.1)​​​.
